Authentication for Slack

Prerequisites

Depending on the authentication type you select, you need one of the following credentials:

OAuth 2.0 Authorization code: User scopes, Bot scopes, and your Slack credentials.
Bring your own OAuth 2.0 app: Client ID, Client secret, User scopes, Bot scopes.

For creating a private OAuth2 app, follow the steps mentioned in the Slack documentation.

To be able to create a connection, you need to be a member or a guest of a Slack workspace.

Note: If you create a connection using Bring your own OAuth 2.0 app, there are some additional steps you must take when using the Button Clicked event. Refer to Using Button Clicked with Bring your own OAuth 2.0 app authentication for more details.

Add the connection for Slack

To create a connection to your Slack instance, you need to perform the following steps:

Select Integration Service from Automation Cloud^TM Public Sector.
From the Connectors list, select Slack. You can also use the search bar to narrow down the connector.
Select the Connect to Slack button.
You can choose between two authentication types: OAuth 2.0 Authorization code or Bring your own OAuth 2.0 app.
1. If you select the Bring your own OAuth 2.0 app method, enter the required credentials and select Connect.
2. If you select the default OAuth 2.0 Authorization code method, follow the steps below.
Review or change the Bot scopes and/or the User scopes as per your requirements or use case. This step is optional. You can use the default scopes to create the connection.
Select Connect.
Select the correct workspace from the top-right corner of the screen. The connection performs actions only for this selected workspace and its respective channels.
Select Allow. With access to your Slack account, UiPath can do the following:
- View content and info about you.
- View content and info about channels and conversations.
- View content and info about your workspace.
- Perform actions as you.
- Perform actions in channels and conversations.
- Perform actions in your workspace.
Your connection has been added.
